Fixedly secured to the-upper portion of whorl I3is a lowerflier H which comprises i This: invention relates to acombined twister and packaging machine whereby the fliers impart twoturns per revolution to the yarn being wound thereon, and is so designedas to stand in a vertical position and therefore being capable of beingmounted on a conventional twisting fram roving frame and the like by thesimple addition of atop bolster rail.

-;It-is an object of this invention to provide a acombined twisting andpackaging machine for yarns wherein the yarn can be passedfrom thedraftingv rolls in fiber preparation machinery twice as fast as in atwisting machine employing ring twisting because ringfltwisting impartsonly one turn or twist perxrevolution whereas the present inventionimparts two turns per revolution to the yarn being not only twisted,butpackaged at the same operation. It is another object of thisinvention to provide anapparatus adapted to be associated with,

fiber preparation machinery which will-wind and twist the yarn in one.operation and which is applicable to roving frames, spinning frames,

twisting frames and the like, the spoolinglopera tion'being eliminatedas the yarn is twisted and placed on proper yarn holders such as tubes,spools and thelike, at the apparatus is applicable to roving frames,spinning frames, twisting frames and the. like, since ittakes the yarndirectly from the drafting" rolls of thesefrarnesrand twists the sameand packages it at oneoperation.

Referring more specifically to the drawings,-

the numeral Ill denotes the lower rail of a twister which has mountedtherein a flanged bolster II, this bolster being secured to the rail- IDby any suitable means such as nut l2 disposed beneath the rail. BolsterH has rotatably' mounted therein a spindle which l spindle has securedon the upper end thereof a the same operation, and

invention having member H and a counter weight member l6. Member l5extends upwardly and is forked at its upper end. 1 i

Secured as at ll to one of the forked members is a flexible member I8jwhich is composed of any flexible material such as rubber tubing andthe like and secured to the upper end of member l8 as at I9 is arm 20ofthe upper flier 2|, said upper flier 2| having a counter weight arm 22integral therewith disposed on the opposite side of the V pivot pointfrom member 20. y The upper flier 2| has a spindle which isrotatablymounted in bearing 29 which bearing is secured in top rail 30.Fixedly secur'edonthe upper, end of spindle 28 is another whorl 3| whichis adapted to be driven by the same cylinder that drives the lower whorll3. i

.Thellower portion of flier M has projecting up- ,spool rack remainsstationary.

End thrust bearing 34 assumes the weight'of the spool rack as the flierl4 rotates;: Spool rack 35 has two arms 36 and 31 which extend upward-1y and'thenagain laterally and are joinedtogether again at the hubportion 38. Fixedly se cured in. hub 38, by any. suitable means such asset screw isa vertically disposed rod 39, The

upper end of member39 is forked and has two projections 4| and 42 whichare adapted to fit into cavities 43 and 44 respectively of lockingdevice 45. -Member 45 has integral ther ewith an upwardly projectingmember 46 which is adapted to fit into the central'portion of spindle28. By

referring to Figural it is seen that the spindles in bolster H and*themember 39 are in direct alinement whereas, the spindle 28 which isrotatably mounted in the top rail isoff-center Since the spool rackremains stationary at all times, and the fliers l4 and 2| are constantlyrotating, the resilient member I8 must be provided because the fliers l4and 2| rotate about two different centers, in other words, the twofliers are not concentric. I 7

By placing the upper spindle 28 off-center from the lower spindle, andproviding locking member 39 with prongs 4| and 42 thereon which fit intothe second locking member 45, it is impossible for the spool rack 35 torotate and it is thereby held in stationary position at all times,regardless of the speed of the fliers l4 and 2|.

The upper end of member l5 has a prong 53 which extends upwardly andlaterally and has integral with the end thereof a collar 54, said 001-wardly from the central portion thereof, a collar lar 54 being adaptedto rotate around the lower spiral gear 55 cut therein which is adaptedto mesh with a pinion 56, said pinion 56 being fixedly secured on shaft51. The shaft 51- has one end rotatably mounted in housing 58 and itsother end rotatably mounted in the cover 59 which is secured to housing58 by any suitable means such as screws 60. Pinion 56 also meshes withanother pinion 6| which, in turn, is fixedly secured on shaft 62, saidshaft 62 being also rotatably mounted in housing 58 and cover 59. Abeveled gear 63 is fixedly secured on=shaft 62 wh=ich meshes with asecond beveled gear 64 fixedly secured on shaft 65, said shaft 65 beingrotatably mounted in a: bearing- 66 which is integral with the housing58' and' another bearing 68 which is integral with the upper portion ofspool rack 35'. The housing 58 encloses the gears- 55', 56, GI, 63 and64 and normally rests on the top of spool rack 35 and isse'cure'dthereto: by any suitable means'such as stud bolts 69% Fixedly mounted onthe end of shaft 55 is a worm gear 16' which meshes with apinion I'I'.Pinion 'ITis fixedly mounted on the upper end of shaft II? which shaftis rotatably' mounted in bearings 1'9and80 which are" integral withmember 3t? of spool rack 35.

The lower end of shaft [8 has fixedly secured thereon a beveled gear 8*Iwhich meshes with" another beveled gear 82 said beveled gear 8'2 beingfixedly secured on one end of roller 83. 'Roller 83 has its endsrotatably mounted in members 36- and 3'! of spool rack 38, and a tube ofyard 8d- 35 normally contacts this roller. andiis rotated there'- by.The tube' of yarn is rotatably' mounted on a transverse shaft 85- whichis sl-idably mounted in slots 86 and 81' cut in vertically disposedmembers 36 and 31 respectively. These slots are identical' in allrespects and a showing of one is deemed sufficient. (See Fig. 2

One end of shaft 85' has a tension spring 88' se'-r cured theretowhichextends' downwardly and is secured to member 35 as at 89; The otherend of shaft 85*hasa similar spring 99 secured thereto which alsoextends downwardly and: is secured as at 91 to'vertically'disposedmember37. It is seen: that these springs normally pull the shaft 85' and thetube of yarn 84, which is rotatably mounted therein, downwardlyincont'act' with the roller 83 at all timesand as the roller rotated thetube of yarn to cause the yarn to uniform rate; v

Beveled: gear 82 also meshes with another beveled gear 92" which isfixedly secured on the shaft 93,- this shaft 93' is rotatably mounted inbearings 84 will also be rotated be wound on the spool at a 94' and 95which are integral with the vertically disposed member 36: I

Fixedly secured on the lower end of shaft 93 is a beveled gear 96 whichmeshes with a beveled gear 91, said beveled gear 9'! beingfixedly'mounted-on one end of traverse 98. Traverse 98 has its endsrotatably mounted in members 36 and 31, and has a suitable reversedgroove cut therein which is engaged by one end of traverse 99. Traverse99 is slidably mounted on bar I09, which bar has itsends secured also invertically disposed members 36 and 3'1. Rotatably mounted'intheleft-hand end of traverse 99"; (Fig. 4),

is a plunger I'BI: which has a flattened lower end fitting into thegroove in traverse 98 and since this member I I' has a flattened portionengaging the groove when it comes to'one' end of the reverse groove, themember is free to' rotate and to start the traverse travelling in theopposite direction on the rod M8. The right-hand portion of traverse 99,as seen in Figure 4, has pivotally mounted therein a thread guide I62which projects upwardly and has an eyelet I93 in the upper end thereofthrough which the strand passes to the spool of yarn 94. A bar I04supports the member I92 and prevents the clockwise rotation of threadguide. 99 about the rod I90 and likewise has its ends fixedly secured inmembers 36 and 31.

It is seen in Figure 1 that as the traverse 98 is rotated that thethread guide I02 will be travversed back and forth due to the reversegroove in the traverse 98, and cause the yarn to be wound properly uponthe" spool of yarn 84 A strand of yarn I05'is fed to the apparatusthrough the bore its in the spindle 28'.

From the spindle 28 the yarn passes through eyelets I97 which aremounted on fliers II and I4 and then goes into another bore H18 in thelower side of flier I4. From this bore the yarn passes through avertically disposed bore me in the lower portion of spool rack 35 andupwardly to another eyelet I I0 secured were thread guide I92. From thispoint the yarn goes- 'through the eyelet. we in the upper end of thethread guide I92 and'onto the cone of yarn 84 For each revolution offliers I4 and 24 the yarn I95 is given two turns twist.- The first twistis given as the yarn leaves the drafting rollers to" enter bore it andthe second twist is' given be-- tween bore I99 and eyelet I93; Sincethis appa' ratus provides two turn twist per revolution of the flier,the production is doubled because" the" yarn can be passed from thedrafting rolls twice as fast in the process of ring twisting where oneturn twist is given per revolution of the ring traveler.

As the fliers I4 and 2I are rotated. the collar 54 and worm gear 55 arelikewise rotated, thereby .rotating the pinions 56 and 6| and thebeveled gears 63 and 64. This will cause the shaft 65 with the worm gearI6 on the end thereof to likewise rotate which will, in turn, rotate theshaft 78, the'bevel'ed gears BI and 78-2 to caus'ethe roller 83 torotate the tube of yarn 8'4 and to draw the thread thereon.

In themeantime, the beveled gear 92 will ro tate the shaft 93 and causebeveled gears 96 and 97 to rotate traverse 98 and traverse the threadguide 96 to properly place the yarn on the tube. It is thus seen thatmeans have been provided whereby the spool rack 35' can be heldstationary at all times as the flier frames I4 and- 2t rotate at a veryhigh speed.

This is done by placing the top spindle on adifferent center from thebottom spindle and providing the locking device shown in Figures 4 and5-. This construction also allows the spool rack and spindles to beoperated in a vertical position instead of a horizontal position. Whenmounted in a horizontal position the spool rack has hereto-- fore beenheld in stationary position by means of weights or gravity, which is notsatisfactory due to varying frictional forces in the bearings.

Since my apparatus winds and: twists the yarn in one operation and isapplicable to roving, spinning and twisting frames, the spoolingoperation is eliminated. The apparatus is applicable to roving, spinningand twisting frames since it of these frames.
